`imatented Jan. 16, 1940 UNITED STATES vPA'reN'r OFFICE- y 3 Claims.

The invention relates to a container and more provision of a device of this character, wherein the lid or cover fitting the body of a container, jar or the like in association with a rubber gasket or ring creates a vacuum seal and such lid or cover can not be removed from the body of the container, jar or the like except by the breaking of the seal to relieve the vacuum interiorly of said container, jar or the like. This seal is broken in a novel manner and through the instrumentality of a key.

Another object of the invention is the pro vision of a device of this character, wherein on the application of the lid or cover to the body of the container, jar or the like the airA will be expelled from the interior of said container, jar or the like for eiecting a Vacuum `seal of the lid or cover thereon and assuring against leakage at the lid-or cover so that the contents of the container, jar or the like will be maintained fresh.

A further object of the invention is the provision oi a device of this character, wherein the rubber ring or gasket associated with the body of the container, jar or the like and the lid or cover 4therefor will be iirmly held against displacement and such ring or gasket will be compressed in its seating between the bodyand the said lid or cover for a positive sealing of the container, jar or the like while o n the breaking of the vacuum within the container, jar or the like, the lid or cover can be readily removed. The breaking oi` the vacuum is eiiected by a key which punctures the rubber ring or gasket and the puncturing thereof does not destroy the further use of such ring or gasket for sealing purposes in its use with a container, jar or the like.

A stilliurther object of the invention is the provision of a device of this character, wherein the key in its construction is such in the use thereof to break the seal between the lid or cover and the body of the container, jar or the like, or, in other words, destroy the vacuum'within the said body and thus enabling the lid or cover to be removed without undue labor.

A still further object of the invention is the provision of a device of this character, which is simple inits construction, thoroughly reliable and eilicient in operation, assuring a positive Huid-tight seal between the lid or cover and the body of the container, jar or the like, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the pre'- ferred embodiment of the invention and pointed out in the claims hereunto appended.

Figure 7 is asectionai view taken on the line l-l of Figure 6 looking in the direction of the arrows. i Figure 8 is a fragmentary enlarged vertical sectional view showing a' keypuncturing the seal of the lid or` cover on the body of the container, jar or the like.

Figure 9 is a sectional view taken on the line 9-9 of Figure 8 looking in the direction of the arrows. I Similar reference characters indicate corresponding partsthroughout the several views in the drawing. j

Referring to the drawing in detail, A designates generally a portion of the body of a container, jar or the like, preferably of the glass type, and havin g,as usual, the open mouth, which is formed with an outstruck annular rim IIJ having an internalcountersunk annular shoulder II providing a seat within the mouth or open end of the shoulder I I is downwardly beveled for a purpose presently described.

'Ihe mouth or open end of the body constituting the container, jar or the like A is adapted to be closed by a removable lid or cover I3, which is of a diameter` corresponding to the external diameter of the rim I of the said body and formed in the bottom face of said lid or cover I3 is an annular groove or channel I4 which is adapted to register with the countersunk shoulder II inthe rim I0 while inwardly of this channel or groove I4 and depending from the bottom face of the lid or cover is an annular backing wall I for a resilient ring or gasket I6, which is tted Within the groove or channel I4 and is adapted for contact with the shoulder IIin the mouth or open end of the body for eiiecting a seal between the lid or cover and said body constituting the container, jar or thev like. The backing wall said body. The side wall I2 of the seat created by 'to I the lid or cover I3 the air within the body of the container, jar or the like A can be expelled therefrom preceding the final seating of the lid or cover upon the body, this expulsion of air being indicated by the arrows shown in Figure 4 of the drawing, the nal seating and sealing of the lid or cover being shown in Figures 5 and 8 of said drawing.

The ring or gasket I6 is relatively deep and has a width corresponding to the width of the channel or groove I4 and by the presence of the rim I on the body of the container, jar or the like A and the wall I on the lid or cover a fourpoint contact of this ring or gasket I5 will be had therebetween. At the same time an overlap is assured with respect to the joint between the lid or cover and the body of the container, jar or the like A so that a perfect fluid-tight seal is had therebetween.l

'Formed in the rim I0 is a transverse opening or notch I8 while adapted to register therewith is'an opening or notch I9 formed in the backing y wall I5 and carried entirely therethrough transversely of the same. These openings or notches .I8 and I9when,in alignment with each other on the sealing of'the lid or cover upon the body, constitute a way for a puncturing blade 20 of a key 2l', the blade being formedwith a pointed, free or piercing-end 22. The blade 20 alsol` is provided with-an elongated slot 23v so Athat when the said blade is pierced through the ring or gasket I6 an air way is created to permit entrance of air interiorly of the body of the container,=jar or the like A, when the lid or cover is sealed thereon and in' lthis way the vacuumis broken within said'body andthe seal-'destroyed so that the lid or cover can bevreadily removed from the open end or mouth of the container, jar or the like.

The puncturing or gasket I6 does not destroy the further use there-" of because the puncturedarea can be shifted away from the points of the openings or notches I8 and I9 hereinbefore mentioned and thus a perfect fluid-tight seal may be had between the lid or cover and the body of the container, jar or y the like in the-further use of said ring or gasket.

About the notch or'openng I9, that is, the upper end thereof and at'oppositesides of the same is the rib formation 24, whichl bites into the ring or gasket I6 for preventing the creeping thereof or undue expansion of the same sothat positive piercing or puncturing of such ring or gasket at the area thereof confronting the openings ornotches I8 and I9 can be assured. This rib formation 24 also creates a seal in conjunction with the ring or gasket I5 about theentrance way for the key so that air from without can not make entrance at this pointA to within the container, jar or the like, this point being the weakened area thereof. The key 2l at theinner end of the blade2i! has formed-therewitha shoulder 2 5 which limits the insertion of the blade-in the ring or gasket I6 when the latter ispunctured or 'pierced so that a positive admission of air from without to within the container,jar or thelike is assured in that the slot 23 in said bladeV will not be-closed, which would be the case if the blade were inserted too far within the container, jar or the like during the Ipiercing operation.

piercing of l the lring or .alsa-seo Straddling the lid or cover I3 when applied to the open end or mouth of the body of the container, jar or thelike is a spring clip or clamp which involvesa downwardly bowed springy intermediate portion 25 and downturned hooklike terminal legs 26, respectively, the clip or clamp, when bridging the lid or cover I3, permits a rise of the latter from the-jar when within a cooker so as to permit the automatic escape of pressure within said container, jar or the like and thus relieving any resistance of the lid or cover becoming sealed during the cooling of the contents of the container, jar or the like and a four-point seal of the ring or gasket I6 will take place between the lid or cover and the said container, jar or the like by vacuum sealing action.

What is claimed is:

1. A container of the kinddescribed comprising a body having a mouth opening provided with an internal annular shoulder, a lid for the mouth opening and having in its bottom an annular vgroove inset from the outer peripheral edge thereof` forregistering with the shoulder, an annular backing wall depending from the bottom of said lid inwardly of said groove and inwardly` beveled, a resilient sealing ring fitting said groove and disposed concentrically about and against the said beveled wall for seating engagevbacking wall interiorly of the body when said lid is sealed thereto, and a rib about the way in the backing wall on the side thereof next to the sealing ring when engaged in the annular groove in said lid for-biting into the said ring.

2. A container of the kind described comprising a body having a mouth opening provided with an internal annular: shoulder, alid for the mouth opening .and having in its bottom an annular groove inset from the o uterperiphery thereof forregistering with the said shoulder, a backing wall depending from the bottom of said lid inwardly of said groove, a resilient sealing ring tting said groove and disposed about and againstsaid backing wall for seating engagement against the shoulder on the placement of the lid upon the bo'dy at the mouth opening, a wallv formed at vthe mouth opening and meeting the said shoulder, the said lid and the backing wall being .provided with a keyway intersected by the lay of the ring and communicating with the interior of the body through said wall when said lid is sealed thereto, and a rib at the way in the backing wall on the side thereof next to the sealing ring when engaged in the annular groove in. said lid.

3. A4 lid for an open mouthed container comprising a body portion having in itsbottom an annular groove inset from theV outer peripheral edge thereof adapted to receive and seat a packing ring, a backin'g'walldepending from the bottom of said iid inwardly of said groove adapted to support such packing ring through a major portion of, its area, a lateral key way in said-lid and backing wall intersecting. the packing zone, and a rib-on said backing wall at said key way on the side thereof nextto the sealing ring when engaged in the annular groove of said lid.
